Silverfang and Arcborne

These pronged daggers are scarred and nicked with use, but their magic is just as potent as the day they were forged.
Silverfang - This blade is so sharp that even a gentle caress of the edge will draw blood. Whenever you deal damage with this weapon, Silverfang's keen edge flicks in and out of your target easily, giving you an additional attack.
Arcborne - This blade's edge crackles with electricity. Whenever you deal damage with this weapon, roll an additional 1d10 lightning damage.
